A QoS Distributed Transport Service

A distributed transport service in a global Quality of Service (QoS) framework
over IP based protocols is presented in this paper. A distributed strategy of
dynamic transport agents located along the end-to-end path is suggested. QoS
management focused on transport layer based QoS adaptation for tolerant
multimedia traffic is provided by the designed mechanisms.
Tradeoffs between traffic QoS requirements and network operation conditions
are studied in order to improve application level QoS parameters.
It is in the context of Heterogeneous Long Fat Pipe Networks1 (HLFNs) that
we show important improvements both on application QoS parameters and network
resources utilization.
